Frederick Pepys Cockerell was a British architect and the second son of Charles Robert Cockerell, also an architect, whose favour for French architecture and sculpture in architecture was a major influence on Frederick. He studied at Winchester College and at King’s College London, and spent time sketching and training in France in 1850 and 1851-53 before returning to join his father’s architecture practice in 1856. He entered the 1863 competition to design the Albert memorial, and that in 1866 to design the National Gallery, though he won neither of them. The Royal Institute of British Architects elected him an associate member in 1860, a fellow in 1864, and honorary secretary in 1871. He was a trustee of Sir John Soane’s Museum as well as a member of the Athenaeum Club.
In 1867 Cockerell married Mary Mulock, daughter of Thomas Homan Mulock of Bellair, King’s county – the couple had six children. His sudden death in Paris in 1878 was followed by a funeral procession followed by the French architects Duc, Lefuel, Hardy, Pelechet, Daumet, and Vaudremer and burial at the Auteuil cemetery, Paris.
